This is Episode 11, picking up after storing records without warping. The first ten episodes covered how to buy, handle, and keep records. The next stretch is about telling them apart, and it starts here, because the same album can exist in a dozen versions that sound and cost wildly different.
Two copies of the same title, same cover art, same tracklist, can be separated by forty years and two hundred dollars. Knowing which one is in your hands is the skill that turns a shopper into a collector.
The Four Words People Mix Up
Pressing is a manufacturing run. One stamper, one plant, one batch of records. An album can be pressed hundreds of times over its life.
First pressing is the earliest commercial run, made from the original lacquer, usually in the album's release year. This is the one collectors chase.
Repress is a later run of the same edition, using the same or similar mastering. The record is essentially unchanged, it was just made again because the first batch sold out.
Reissue is a deliberate new edition, usually years later, often with new mastering, new packaging, and sometimes bonus material. A reissue is a new interpretation of the album, not just a new batch.
Bootleg is unlicensed. Nobody involved in making the record is being paid for it.
Reading the Deadwax
The deadwax, also called the runout groove, is the smooth band between the last track and the label. Scratched or stamped into it are the matrix numbers, and they are how a record identifies itself.
Tilt the record under a light and read the etching. You are looking for a catalog number, often followed by letters or digits that indicate which lacquer and which stamper made this specific copy. Some plants stamp them, some cut them by hand, and a few mastering engineers signed their work there.
These markings are the only reliable way to identify a pressing. Cover art gets reused. Labels get reused. Barcodes are absent on older records entirely. The deadwax is the fingerprint.
How to Actually Use This
Photograph the deadwax with your phone, then search the etching on Discogs alongside the album title. The database will usually tell you the country, year, and plant within a minute. Episode 17 covers Discogs properly.
When a First Pressing Actually Matters
Here is the part most guides skip. A first pressing is not automatically better.
It matters when the original was cut from the master tape and later editions were not. It matters when the tape has degraded in the decades since, so no modern reissue can equal what the original captured. It matters when the original mastering had a specific character that later engineers flattened or brightened.
It does not matter nearly as much when the first pressing was rushed, when the plant was cutting corners, or when the album is from an era of thin, noisy vinyl. Plenty of 1970s originals sound worse than a careful modern reissue, because the reissue was cut with more care, pressed on better vinyl, and given more room across two discs.
The honest rule: a first pressing is worth paying for when the chain from tape to groove was shorter than it is today. It is worth nothing extra when it was not.
Spotting a Bootleg
Bootlegs are not always obvious, and some are decades old and collected in their own right. The usual signals:
- No barcode and no legitimate catalog number, on a record that should have both
- Blurry cover art, which happens when a jacket is photographed rather than printed from source
- A label design that does not match anything the actual record label ever used
- Sound that is clearly sourced from a CD or a broadcast, with an obvious digital ceiling
- A live album from a famous show that no label ever released
The strongest tell is that the pressing exists at all. If a legendary concert is available on vinyl and no official release was ever announced, you are holding a bootleg.
What to Do at the Bin
Decide what you want from the record before you pay a premium. If you want to hear the album, buy the cleanest copy of any decent pressing and spend the savings on more records. If you want the specific sound of the original, verify the deadwax before paying original prices.
And check condition first regardless. A first pressing in rough shape is worse listening than a clean reissue, and no pressing pedigree survives a deep scratch. Episode 7 covered record grading if you need a refresher, and our full record cleaning guide is worth reading before you write off a noisy copy, because a lot of what sounds like damage is dirt.
